White vs. Warm Balancing

[Bob Mark]

You should balance to a white card, not gray. The warm cards are to cheat the camera toward red (warm) by removing some blue in the picture. You can do this in your camera profiles, too by adjusting the color matrix. This might be helpful.

Nothing wrong with using a true gray card for white balance. the process merely requires a target that is devoid of color! An advantage of gray might be that it’s probably less susceptible of reflecting another strong color in front of it?

For your green screen shoots, if lighting with tungsten balanced photo quality lights, preset 3200 is a good choice.

I always recommend flipping back and forth between preset and the AWB while observing on a properly adjusted monitor and choosing the best look. It might be counter intuitive but still correct.

Here’s a run down on what Vortex Media cards offer.

Take a look at page 6 to see how each card effects the white balance.

For another option you can use a Rosco Jungle Book to manual white balance.

Thanks for all your feedback.

I have decided to try out the WarmCards 3.0 (also included a pure white and grey card). Will let you know what my test results are.

Thanks again
